Question

我在表格中有一个XMLTYPE列。我想根据限定的where子句从表中选择行。我可以在我将属性xmlcast到值的地方运行语法。我使用XMLExists时无法返回任何行。我试过[returnCode]和[@returnCode]。我不确定我是否在query_string中正确指定了命名空间，我所拥有的是我在网络和Oracle OTN上找到的示例。其他似乎并不多。

FROM 
PRDOPTDIR113.OPTIM_TRANSACTION_CONTENT T
WHERE
XMLExists('declare namespace optns="http://www.ibm.com/optim/report/v11.3.0.0"; (::)
          /optns:OptimReport/CommonContent[@returnCode="0"]' PASSING T.XMLDATA)
--XMLCAST(extract(T.XMLDATA,'/OptimReport/CommonContent/@returnCode',
--            'xmlns=http://www.ibm.com/optim/report/v11.3.0.0') as INT) = 0
;

有什么建议吗？
